The problem is that I never got a good answer with a reference. Capt. Crunch says one thing, Major Tom says another. I don't want Sgt Pepper writing me up. I didn't go to the BBC School of Law so I'll keep looking. If the guy calls me back, I'll post his response and take his word for it.
Well, just got off the phone. He said it doesn't need to be worn, just have it in the boat. That's Oklahoma. Your results may differ. Surprised he called back so soon.
